LONDON (AP) — Arsenal’s transfer spree continued with the signing of England forward Noni Madueke from Chelsea on Friday. He is Arsenal’s fourth signing of the offseason after midfielders Martin Zubimendi and Christian Norgard and goalkeeper Kepa Arrizabalaga.

Arsenal have confirmed the shirt number for summer signing Noni Madueke. Madueke joins Arsenal from London rivals Chelsea in a deal that could be worth up to £52m if certain add-ons are met. The winger becomes the club’s fourth signing of the window following on from Martin Zubimendi, Kepa Arrizabalaga and Christian Norgaard.

Madueke joins a select group of 18 senior players to have crossed the divide and left Chelsea for bitter rivals Arsenal. Petr Cech, Kai Havertz, Jorginho and, of course, Kepa are just some of the names to have made the controversial move from west to north London in recent memory.
